We find exact and asymptotic formulas for the average values of several statistics on set partitions: of Carlitz's q-Stirling distributions, of the numbers of crossings in linear and circular representations of set partitions, of the numbers of overlappings and embracings, and of the numbers of occurrences of a 2-pattern.
